Design And Reserch Control System For The Shipborne Stabilized Platform

The change of the direction and swaying of the ship will give rise to distance, which influences the normal operation of the platform system. In this case, Shipborne stabilized platform can isolate the disturbance of the carrier and ensure the stability of the inertial frame in the platform system, so as to make the equipment of the platform track the target accurately.This paper conducts a research on the control system of the two-axis shipborne weapons platform. First, the general design scheme of the stabilized platform for the shipborne weapons was proposed. After the analysis of the kinematics and dynamics of the stabilized platform, a feedback control technique with two velocity loop and position loop was established, and then the proper selection of the system equipment was completed at last.Second, based on the general design, a three-loop controller with two velocity loops and a position loop can be derived after the analysis of the mathematical models of the system, which has been demonstrated by the simulation results.Considering the limit of the traditional PID controller and the feature of the shipborne stabilized platform, a control algorithm combined the PID and Neural Networks was proposed in this paper. The simulation results indicated that this control algorithm with special anti-disturbance ability can improve the dynamical performance of the system and reduce the steady state error.Finally, the realization in engineering of the servo controller was introduced in detail. The hardware circuit, which consists of servo controller and drive, was designed in this paper. Based on the available hardware circuit, the software designing of the system and the test of the whole stabilized platform system were completed. The results of the test have indicated that the stable platform can meet the requirement of the performance.
